Detroit-based American Axle and Manufacturing Holdings Inc. announced last week its plans to invest $100 million in its Three Rivers facility.

The investment is expected to create 500 new jobs at the plant by the end of the year.

According to a company media release, the investment is part of the installation of new production lines, multiple assembly stations, paint-line modifications, increased shipping-and-receiving capacity, and upgrades to the plant's lobby and businesses offices.

Company officials said the addition centers on new technology, specifically the company's patented EcoTrac Disconnecting All-Wheel Drive system.

The new jobs would bring American Axle's workforce to about 1,300 by the time new hires are brought aboard.

Company president and CEO David Dauch, in a media release, stated the business launch has been two years in the making.

"Now we are in a growth mode and hiring hundreds of associates," Dauch said. "This is exciting news for the state of Michigan, the city of Three Rivers and AAM."

In 2012, American Axle created more than 300 jobs in Michigan and invested $50 million. Company officials said the investment represents technologically advanced machining equipment, research and development laboratory equipment and other upgrades.

A job fair for manufacturing positions will take place 9 a.m.-1 p.m. Feb. 16 at the Kalamazoo County Michigan Works Service Center, 1601 S. Burdick St., Kalamazoo.
